$2\mathrm{.}4$ Three structural members $A,B,$ and $C$ of a steel truss are bolted to a gusset plate as shown. The lines of action $($line through which the force passes$)$ of all three members intersect at point $0,$ making this a concurrent force system. Determine graphically $($parallelogram law or tip$-$totail$)$ the resultant of the three forces on the gusset plate. Use a scale of $1mm=400N.$

Note: The resultant must be denoted by a magnitude and direction. $$
